Set-Off & Carry Forward of Losses – Advanced Strategy Guide FY 2025-26

Set-off and carry forward provisions represent one of the most powerful tax optimisation tools available under the Income-tax Act. While most taxpayers focus only on deductions, seasoned tax planning revolves around strategic utilisation of losses across years.

1. Understanding Set-Off of Losses

• Intra-head set-off: Within same head
• Inter-head set-off: Across heads

2. Intra-head Set-Off Rules

Loss Type	Allowed Adjustment
Business Loss	Any business income
Capital Loss	Within capital gains
House Property	Within same head

3. Inter-head Set-Off Rules

Loss Type	Can be Set-Off Against
House Property Loss	Any income (max ₹2L)
Business Loss	Any except salary
Capital Loss	Only capital gains

4. Carry Forward of Losses

Loss Type	Years Allowed
Business Loss	8 years
House Property	8 years
Capital Loss	8 years
Speculative Loss	4 years

5. Capital Loss Rules
